POLITICIANS’ personal lives are never completely their own, nor should they be. But in a decent society, a zone of privacy should be drawn widely enough to shield a politician’s kids from the hurly-burly of their parent’s campaign.

In this year’s campaign for 45th Legislative District, Position 1, that line has been obliterated by a sleazy third-party organization. The New Majority PAC has spent $50,000 to splash allegations from the divorce file of state Rep. Roger Goodman, a four-term Democrat from Kirkland, across TV ads, campaign fliers and social media.

The only serious allegation in this muck — that Goodman drove high on marijuana with his kids in the car — is not substantiated by police reports or Goodman’s driving record. He firmly denies it. Remember, these are allegations from a divorce file.

In a race to churn up more, the New Majority’s hit pieces use Goodman’s children as pawns. Goodman rightly objects and denounces the ads.

So should his opponent, Republican Joel Hussey, who also ran against Goodman in 2012. Instead, Hussey, in an endorsement interview with The Seattle Times editorial board, essentially shrugged. He lamely compared the personal attacks to third-party campaign fliers in their previous race. The difference is those attacked Hussey’s political positions on issues such as abortion, not his personal life.

That’s where campaigns should be centered — on issues.

If voters see these sleazy third-party fliers plop in their mailboxes this election, toss them in the trash where they belong.
